There was a troubling article in the Washington Post Thursday documenting the trend toward less accurate tornado warnings from the National Weather Service as compared with just ten years ago.here. Jason Samenow wrote a great article on a complex subject.
However, there is one comment I wish to make and that is to advance another hypothesis as to the startling decline in NWS tornado warning accuracy: retirements. Most of my contemporaries from college and elsewhere who spent their careers in the National Weather Service retired several years ago. As a friend of mine says, "you can't teach experience." So, I believe the NWS may have an "experience gap" in addition to one or more of reasons offered in the article.
At AccuWeather Enterprise Solutions, we do not have the decline in tornado warning accuracy that is affecting the National Weather Service.

P.S. To Harold who commented below. May I respectfully suggest you read the article again? A lead time of six minutes recently as compared with 13-15 minutes before is a less useful warning. A 20 point decline in issuing a tornado warning before one appears (POD=probability of detection) against a 5 point improvement in false alarm rate (FAR) is a less accurate warning however you define it.
